The Polar Service Center in Phoenix, AZ, has received ASME “R” stamp certification. The certification means the facility is approved to make repairs, including welding and bodywork, on DOT-coded tanks and pressure vessels.

The ASME R stamp is issued by the National Board of Boiler and Pressure Vessel Inspectors. Certification involves a detailed audit of a facility’s procedures and quality systems.

“The National Board R stamp certifies our Phoenix location to test and repair all makes of coded pressure tanks, including welding and bodywork on DOT 406, DOT 407, and DOT 412 tank trailers,” said Mike Evans, president of Polar Service Centers. “It is an important capability especially for customers in Maricopa County, which has stringent cargo tank inspection and integrity requirements.”

The 8,000-sq.-ft. Phoenix facility opened in July 2011.
